**Incumbent Democrat Hank Johnson faces Republican James Duffie in Georgia’s 4th Congressional District on November 3, 2026, with a runoff possible December 1 if no candidate reaches a majority.** The district’s strong Democratic lean (D+27 Cook Partisan Voter Index) and consistent “Safe Democratic” or “Solid Democratic” ratings from forecasters such as Cook, Sabato’s Crystal Ball, and Inside Elections underpin trader expectations of an outright win. Johnson secured renomination in the May 19 Democratic primary with roughly 79% of the vote, while Duffie advanced unopposed on the Republican side. Johnson’s prior general-election margins have routinely exceeded 50 points in this Atlanta-area district covering portions of DeKalb, Rockdale, and Newton counties. No competitive polling shifts, major campaign developments, or external events have altered the outlook in recent weeks, leaving the race structurally noncompetitive. Early voting began October 13. These factors produce the current 92.2% market-implied probability that a first-round majority will be achieved.
